Specification forming part of Letters PatentNm 39,976, dated September'l, 1863.

by declare that the following is a full, clear,

and exactdescription of the same, reference being had to the accompanying drawings,j forming part. of this speccation, in"which Figure lis a vertical section of the fount ain. Fig.`2 is a plan of thesame, with .the cover removed to show the interior arrangement.

Similar letters of reference indicate corresponding parts in bot/h tigures.

This invention is of that kindi'rom which asolution of supercarbonate of soda and alnixture of sirup and acid are drawn separately vinto tile glasses.

'The invention consists ilr a novelarrange' .l menttnan airfchmnher,l inrombinationwith the tank which `contains the soda solution,

and with a suction and force pump and `elerated draft-tube, wher` by a quantity of the solution is retained in the vessel under suf? icientpressure to force it through the drafttnibe, andis Ikept cool for delivery to the said t e. i

To enable others skilled in the art to make and 'use my'invention, `I will proceed-t devscribe its construction and. operation.

A is an. upright box or sta-nd, ol' suitable l1 ight to form a' counter, and of suitable size lo contain the large tank B, in which the solution of supercarbonate off soda is made and kept, and-a' numberof smaller compartments',

a` a, for the reception of the sirups containing the-*necessary acid to produce eervescentre, .such sirups either bein gV placed directly into the said compartments or in bottles arfy ranged therein, and being drawn oft' inthe7 usual or any suitable manner.

' 'C is ahinged lid, forming part 0f the-top .of the stand, and, when open, uncogering'the Sirup-compartmentsa a and a portion of the -sodatank B, and permitting them to be filled.

- .H is a iiap, hinged to' the upper part of-,the front of the StandA, and capable of being Avraisedup to the position shown in red outline in Fig. l, to i'orin an extension of the counter, fAor folded down against thev front of lthe stand,

as shown in black' outline inthe-same gure,.-

to be out of the way. D is the suction and Torce pump, arranged A, and operated by 'a hand-lever, 1t'. 'rne suction pipe b of` this pump is connected with .the bottoni of the soda tank B, andthe forcepipe c leads through the bottom of said tank into the bottom of. the air-vessel F, which is arranged Within the saidtank. Thedraft( tuhe' G,. of siphon form, is tted and secured in the top of the air-chamber, and 'passes through the'top of the stand. The lower down into the' air-chamber, in order tliatsme air may always be retained 'in the upper part of said'cham ber and'above the stand A there is provided in ithe said tube a cockd which isopened to draw oli thel soda solution.

The ice for cooling the soda-water is placed directly into the tank B,.around the air-cham-- bar F.

- To set the fountainin operation, the supercarbonate of soda, water, andjce are.l put inV the` tank B. and .the sirups andacidninto-the compartments a a', anda few strokesare given to the pump to dra-wand force the 'soda soin-- and compressa quantityof air in the upper part of the said chamber around the lower soda-water is c-tlled for, a lsuitable quantity of sirupt'is lirst drawn into the glass, which the cock d, said. solution being forced up through thetube by/the pressure of the air in theupper part ot', the chamber F, and that which is drawn being always co0l,.as the airchamber, from which it comes directly, is surrounded by ice. A few strokes ofthe pump will be necessary from time to time'to -replenish the air-vessel with the sol ution and recompressthe air4 therein but ifthe chamber .is of` suitable capacity va. great many glasses may be drawn -without any pumping. being necessary.

to securel by Letters Patent, is-
